SpaceX’s record-setting initial public offering (IPO) marks an important moment for both private and public markets, and for US technology companies. Limited public stock float1, future lockup2 expiration, index inclusion dynamics and a wide range of potential business outcomes will likely keep volatility elevated for the stock. We believe strong returns and a seamless IPO process should set the stage for more mega-cap IPO listings over the next year.

  • Largest IPO on record: SpaceX raised roughly US$85 billion, over three times the prior record set by Saudi Aramco’s US$25.6 billion IPO in 2019.3 The company priced at an approximately US$1.8 trillion market valuation.4
  • Strong first-day demand: Shares finished 19% above the IPO price, reflecting significant institutional and retail demand for one of the most anticipated listings in recent history.
  • Limited float should drive volatility: SpaceX listed 638 million shares (including greenshoe5), or roughly 5% of total shares outstanding. With such a small public float, trading volatility is likely to remain elevated until additional shares become available.
  • Lockup expirations will matter: Early investor, employee, executive and affiliate shares are expected to become eligible for release over the next 180 days. Liquidity should improve over time, though unlock dates may create short-term selling pressure.
  • Its business model carries a wide range of outcomes: SpaceX’s core businesses—space, connectivity, and artificial intelligence—are all on the frontier of technology. Calendar year 2025 revenue of roughly US$18 billion6 is modest relative to the valuation, so execution and the company’s ability to scale these businesses will be central to long-term returns.
  • Index inclusion could create incremental demand: Nasdaq and FTSE Russell rule changes will fast-track SpaceX’s index inclusion, with Russell eligibility after five trading days and Nasdaq after 15 trading days. S&P Index inclusion appears unlikely for at least 12 months, limiting near-term demand from S&P-tracking passive funds.
  • Investment impact: Given the combination of limited float, upcoming lockup expirations, index-related demand, and significant valuation uncertainty, we believe active managers are best positioned to evaluate entry points. More broadly, the success of the IPO will likely reopen the IPO market for other high-quality private companies, including anticipated listings from Anthropic and OpenAI.

SpaceX was chosen for this case study as it is the largest IPO in market history to date.
